WCF的Web.Config - 复制服务名称投掷的错误

Question

下面的代码抛出

命名为相同的密钥“服务”子元素已经存在于相同的配置范围的误差。集合元素在相同的配置范围内必须是唯一的（例如相同的application.config文件）。重复键值：'Marius.Marius_0_0_8'。

现在显然有两个名为Marius.Marius_0_0_8的服务。但是，当我尝试将其中一个名称更改为其他名称时，我得到了一个不同的错误。我假设这是因为该名称必须与.svc中的名称空间&类的名称匹配。

我很累，一直盯着这几个小时。我究竟做错了什么？我所要做的就是打开元数据，以便连接WCF测试客户端。

您正试图为Mex端点声明另一个服务。正确的方法是只有一个暴露两个端点的服务：真正的服务端点和wsdl端点。

<services> 
     <service name="Marius.Marius_0_0_8"> 
      <endpoint address="" behaviorConfiguration="Marius.MariusAspNetAjaxBehavior" 
       binding="webHttpBinding" contract="Marius.Marius_0_0_8" /> 

     <endpoint name="mex" 
       address="mex" 
       binding="mexHttpBinding" 
       contract="IMetadataExchange" /> 
     </service> 

    </services>
